Boosting Local Field Enhancement by on-Chip Nanofocusing and Impedance-Matched Plasmonic Antennas. [PDF]
Nano letters (Print), 2015 Strongly confined surface plasmon-polariton modes can be used for efficiently delivering the electromagnetic energy to nanosized volumes by reducing the cross sections of propagating modes far beyond the diffraction limit, that is, by nanofocusing.

Enhanced Graphical Representation of Electrochemical Impedance Data
Journal of The Electrochemical Society, 2006 Bode plots, corrected for Ohmic resistance, logarithmic plots of the imaginary component of the impedance, and effective capacitance plots are shown to be useful complements to the more traditionally used complex-plane and Bode representations for electrochemical impedance data.

Enhanced Electrical Impedance Tomographyviathe Mumford–Shah Functional [PDF]
ESAIM: Control, Optimisation and Calculus of Variations, 2001 Summary: We consider the problem of electrical impedance tomography where conductivity distribution in a domain is to be reconstructed from boundary measurements of voltage and currents. It is well known that this problem is highly ill-posed. In this work, we propose the use of the Mumford-Shah functional, developed for segmentation and denoising of ...

Diagnosis Enhances, Not Impedes, Boundaries of Physical Therapy Practice [PDF]
Journal of Orthopaedic & Sports Physical Therapy, 1991 Boissonnault and Bass (1-3) contribute an excellent and stimulating description of several "red flag" conditions that should alert physical therapists (PTs) to the presence of nonmechanical sources of pain. They provide an important reminder that pain has many etiologies, and that despite physician referral, patients may have visceral pathologies whose

Selectivity-Enhancement Technique for Stepped-Impedance-Resonator Dual-Passband Filters
IEEE Microwave and Wireless Components Letters, 2019 A class of stepped-impedance resonator (SIR) dual-band bandpass filter (BPF) with selectivity-enhancement cells is reported. These dual-band filtering cells, which are composed of two open-ended transmission-line segments interconnected at the input, are

IEEE Transactions on Antennas and Propagation, 2021 A high-isolation Fabry–Pérot (FP) antenna array with wide bandwidth and high gain is proposed for Ku-band vehicle satellite communications. Each antenna element consists of a pair of tandem circular parasitic patches (TCPPs), a radial gradient partially ...

Sound energy enhancement via impedance-matched anisotropic metamaterial
Materials & Design, 2021 Sound energy enhancement realized by electronic circuit designs plays a vital part in many fields, including acoustic communication, medical imaging, acoustic positioning and sound energy harvesting. The same effect, actually, can be achieved based on anisotropic acoustic meta-structures without electronic components, which has rarely been studied ...

Smart Inverter Stability Enhancement in Weak Grids Using Adaptive Virtual-Inductance
IEEE transactions on industry applications, 2021 An adaptive virtual-inductance feedforward scheme is presented in this article to enhance the stable operation of smart inverters in weak grids. In the developed scheme, the virtual inductance is updated in real time according to an adaptation law to ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Osteosarcoma is a radioresistant tumor that may benefit from stereotactic body radiation therapy (SBRT) for locoregional control in metastatic/recurrent disease. We report institutional practice patterns, outcomes, toxicity, and failures in osteosarcoma patients treated with SBRT.
